From c2a952c6b97b99482533918e9aa1846ff3c60cc7 Mon Sep 17 00:00:00 2001 From: daniel-lxs Date: Mon, 17 Nov 2025 13:40:15 -0500 Subject: [PATCH] fix: preserve tool blocks for native protocol in conversation history Problem: When resuming tasks with native protocol, tool_use and tool_result blocks were being converted to text format (e.g., 'Called read_file with...'), which confused the model and prevented proper OpenAI tool calling format. Root Cause: The tool-to-text conversion logic added in v2.0 for XML protocol was running for all protocols, including native protocol where it shouldn't apply. Solution: Gate the conversion logic to only run for XML protocol. Native protocol now preserves tool_use/tool_result blocks, which are properly converted to OpenAI format (tool_calls/tool role) by convertToOpenAiMessages. Testing: Added 8 new tests verifying both protocols work correctly. All 58 existing tests pass, confirming XML protocol behavior is unchanged. --- src/core/task/Task.ts | 72 ++++--- .../task/__tests__/task-tool-history.spec.ts | 200 ++++++++++++++++++
